ABC News' Devin Dwyer caught up with faculty members and some of the graduates, each of which shook hands with President Obama during the ceremony in Colorado Springs, Colo. Aside from the fact that openly gay members were among the ranks, most cadets interviewed said the impact from last year's repeal was relatively minimal.

"It's pretty much just like any other repeal," one cadet said. "We just got told that this is what's gonna happen, and we all need to be adults about it."

Though several media outlets have noted the lack of rainbow flags or other obvious lesbian, gay, bisexual and transgender (LGBT) pride-relevant symbols during the ceremony, Trish Heller -- who heads the Blue Alliance, an association of LGBT Air Force Academy alumni -- said the reason was obvious.

"The whole thing is we don’t want to be identified as anything different," Heller is quoted by ABC as saying. She noted that her group had connected with at least four members of the class of 2012 who had come out publicly as LGBT, though others likely preferred to keep a low profile. "We want to serve, to be professional and to be symbols of what it means to be Air Force Academy graduates."
